This nothing will bestow upon us save contempt of fortune: but if we attain to this, then there will dawn upon us those invaluable blessings, the repose of a mind that is at rest in a safe haven, its lofty imaginings, its great and steady delight at casting out errors and learning to know the truth, its courtesy, and its cheerfulness, in all of which we shall take delight, not regarding them as good things, but as proceeding from the proper good of man.

Since I have begun to make my definitions without a too strict adherence to the letter, a man may be called “happy” who, thanks to reason, has ceased either to hope or to fear: but rocks also feel neither fear nor sadness, nor do cattle, yet no one would call those things happy which cannot comprehend what happiness is. With them you may class men whose dull nature and want of self-knowledge reduces them to the level of cattle, mere animals: there is no difference between the one and the other, because the latter have no reason, while the former have only a corrupted form of it, crooked and cunning to their own hurt.
